R7000p Nighthawk constant connection drop (wifi and wired)

Hi,

I bought this router about 2 weeks ago and since then I keep getting connection drops. Been googling and found lots and lots of people experiencing the exact same thing. I've tried all solutions - Nothing works for me.. I only enable 2.4ghz, disable mi-mumo, disable guest-network (and SSID), rebooted many times, reset the router settings, I've tried everything and nothing works.

When gaming I get random connection drops (even on ethernet and also on wifi) and I'm 99% sure it is this router as I've never had this problem before and everybody in my house is having it.

My latest firmware: V1.3.1.64_10.1.36 and my router is "R7000p Nighthawk AC2300".

I am thinking of downgrading firmware and maybe that will work? Although I do not know how and to which version? Please any help? I was kind of hoping that disabling guest network (including ssid) and disable mi-mumo will fix it but unfortunately it has not..

Also I am sorry to say but I am frustrated - What are the netgear community doing about this? This is CLEARLY an issue on their router with so many posts experiencing the EXACT same problem and looking at google this has been going on for years - Hello? Years? What's going on? I spent good money on this router and it's having basic problems, I don't even care for any of the features and disabling that still doesn't do it. (Also I disabled port scan and DoS protection - that also didn't fix anything).

Thanks,
